| 摘 要： | 分析了元胞自动机的基本原理和构成，利用元胞自动机原理建立了洪泽湖洪水蔓延模型。模型以栅格空间数据结构作为基础，采用二维元胞自动机模型，确定了元胞空间和元胞状态，建立了洪泽湖洪水蔓延的规则，并根据规则以9邻域方式进行元胞状态的更新。选择性地测试了洪水蔓延模型的计算结果，模型计算数据与实际数据的比较表明，二维元胞自动机模型能够更为简单、快速地模拟洪泽湖洪水的蔓延。

| Abstract: | Basic principle and structure of Cellular Automata (CA) was analyzed, and flood spreading model of Hongze Lake was established by making use of CA rule. Based on grid spatial data structure, adopting the two-dimensional CA model, the cellular space and cellular states were established, and the rule for flood spreading modeling was made. The update of the cellular sate acted according to the rule of 9 neighbors. The computed data by choosing typical index was tested. The results show that two-dimensional CA model can model the flood spreading process more simply and faster. |
